I recently learned that Red Box is offering Free Wednesday Movies in March.
All you have to do is visit their blog, redblog, every Wednesday in March. There will be a code for a free one night's rental. While there, check out their posts. They have posts in many categories including DVD Reviews, Behind the Scenes, In Theaters, Hollywood Chatter and Award Shows.
I know we have been using the free Monday code that you can choose receive by text, or check out any of a number of blogs (like Deal Seeking Mom) that post those codes every Monday. It's a great way to catch up on a lot of movies for cheap, well free. They are also bringing back some classics so that you have more to choose from.
New to Redbox. They offer kiosks with movie rentals for $1 / night. You can rent them for as few or as many nights as you would like. To use a promo code, select rent with promo code. Rental does require a credit card, but as long as you turn it by the next day at 9 pm, there is no charge.
